GeForce GTS 450 1GB vs GeForce GTX Titan

Intro

Compare all of that to the GeForce GTX Titan, which comes with GPU clock speed of 837 MHz, and 6144 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is made up of 2688 Stream Processors, 224 TAUs, and 48 Raster Operation Units.

Texel Rate

The GeForce GTX Titan will be a lot (about 648%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 162432 (648%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 27648 (221%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
